I saw a thread about MP vs v1.2...but what is the difference between 60MT and 60MP? 60MP seems to be the one offered on pioneers website, but I don't know what 60MT is.

I did the solder two points bypass on my N2, I currently have 50mt-v1.0... upgrading the firmware shouldn't be a problem, right?

no idea what the diff is either? can some1 elaborate?
